RECEPTACLE CLOSURE OR RETAINER.

, Specification of Lettem Patent.

Patented. March 2, 1909.

Application filed April 23, 1908. Serial No. 428,816.

To all whom it concern:

Be it known that I, LoUIs ESCHNER, a citizen of the United-States, residing in Philadelphia, Pennsylvania, have invented certain Improvements'inRece tacle Closures or Retainers, of which the f0 lowing is a specification.

My invention relates to means for retaining in-place the closures of jars, bottles, cans, boxes, or other receptacles, the globes of lamps, or other cylindrical bodies, (hereinafter, for convenience, termed receptacles), one object of my invention being to render such means cheap, simple, convenient to operate, and efiective for their intended purpose, and a further object being to adapt the invention for use in connection with hottles or other receptacles which are already provided with closures such as caps, stoppers, corks or the like. The first of these-obects I accom lish by providing on the outer portion of the receptacle adjacent to: the mouth of the same, a series of convex horizontal cams with rounded orcam-like ends, which cams are ada ted to engage with a corresponding set of e astic, concave horizontal cams with cam-like ends formed on the inner side of a ring which constitutes the retainer hereinafter referred to. The second object of my invention I attain by so constructing said ring member that it may engage with a ca stop er, cork, or other form of closure wit Wl'11( 1 a bottle or other receptacle is already provided. and, in some cases, by also providing a separate cam ring for application to the rece )tacle, when the latter itself is not equippe with cams, on. the outer portion of the rim.

In the accompanying drawings Figure 1 is a perspective view of the neck portion of a bottle or jar constructed in accordance with my invention; Fig. 2 is an inverted perspective view of a cap or closure for use in connection with said jar; Fig. 3 is a sectional view of the upper portion of the jar and its cap, said section being taken through cam portions of the cap which are in enga ement with cams on the jar; Fig. 4 is a similar sectional view, but with the section taken through portions of the cap which are not in engagement with camson the jar; Fig. 5 is a perspective View of part of a bottle and a ground glass stopper therefor, and of the various members 0 a retainer for use in connection with said stopper; Fig. 6 is a perspective view showing, in operative relation with one another, the parts represented in Fig. 5; Fig. 7 is a vertical sectional view of the same, and Fig. 8 is a perspective view of a special embodiment of my Invention, and Fig. 9 is a sectional view of the same on a larger scale.

Referring first to Figs. 1, 2, 3 and 4 of the drawings, 1 represents the upper ortion of a bottle, jar, or other receptacle aving, externally disposed thereon, a series of horizontal cams 2, these cams being, by reference, equidistant from one another an separated by spaces 3, each slightly longer than one of the cams on the retainer hereinafter referred to. The cams and the intervening spaces are externally curved or convex in transverse section, as shown in Figs. 3 and 4, and the cams are also rounded or of cam-like form at one orboth ends 4, the latter construction being illustrated in Fig. 1, and being preferred in order that the ring member may be applied by movement either to the ri ht or left. Below thecamsjthe receptacle as a continuous annular rib 5 which is, by preference, provided with a recess 6, as shown in Fig. 1. The ring member of the retainer which cooperates with the aforesaid cam formation on the receptacle may either form a tight, and, if "necessary, a hermetically sealed closure, or, if it does not constitute part of a ca it may serve to confine to the mouth of t e receptacle a packing disk, a cork, a glass cup or stopper or other form of closure which seals said receptacle either hermetically or not, as desired. The cap may carry a brush, may constitute a dispens ing nozzle, or may be constructedin many other known ways de ending u on the use for which the receptac e is inten ed, the special construction of the cap forming no part of my invention.

As shown in Figs. 2, 3, and 4, the ring element 7 of the retainer forms art of a cap 9, and has formed in it inwardly projecting horizontal cams 1O equaling in number an dimensions the cam formations 2 on the receptacle, the inner face of each of these cams being concave to correspond with the convex cross section of the corresponding cam 2, and being rounded or cam-like at each end to facilitate its engagement with said cam 2. The cams 10 donot extend to the lower edge of the ring 7, said lower portion of the ring overlapping and forming a of the same upon the mouth of the receptacle and serves to firmly press this portion of said closure upon said bearing or seat, and thereby effect a secure, and, if necessary, a hermetically tight sealing of the receptacle.

In applying the ring member 7, the same is held so that its cams 10 are in register within the s aces 3 between the cams 2 and the ring is t en passed downwardly until its rib 12 contacts with the sealing disk or other closure upon the top of the jar. The ring is then turned in one direction or the other so as to. bring the forward, cam-like portions of the cams 10 into contact with the cam-like ends of their correspondingcams 2, the latter therefore exerting pressure upon the cams 10 and forcing the same downwardly and outwardly until they are finally seated beneath the cams 2, as shown in Fig. 3, this downward and outward pressure then continuing so as to retain the rib 12 of the cap 9 firmly in contact with the sealing disk or other closure and insure the pressure of the latter firmly upon the bearmg or seat at the top of the receptacle. When the ring 7 is in place, its lower portion contacts with the outer portion of the rib 5-, and thus provides a neat finish and .prevents access of dust or other foreign Thematter to the sealing ring or. disk 13. engagement of the lug 11 on the ring with the recess 6 in the rib 5, besides indicating when the cams 10 are in proper engagement or register with the cams 2, also serves to prevent ready displacement of the ring and thus lessens the risk of its release from the control of said cams. Preferably the recess 6 is formed .in a slight swell or enlargement on the rib 5, whereby the lug-carrying portion of the ring member 7 is slightly expanded as the lug approaches the recess, and the lug is thus caused to snap into the recess, and is retained by the resiliency of the ring member. The relation of the lug and recess may be reversed,without affecting their functions, hence in the claims I have alluded to these members as ofi'sets. The curvature of the outer faces of the spaces'S between the ribs 2 serves, by engagement with the cams 10 of the ring 7 when the same are passed downwardly through said spaces, to temporarily retain the cap in loosely fitting relation to the receptacle and per-- mit escape of steam'or vapor from the latter when its contents are being heated for sterilizing purposes before the final sealing of the receptacle. By pressing up the earns 10 from the ring 7 the e asticity of the entire ring is available to maintain said cams in engagement with the cams 2 of the receptacle,

and by forming the cams above the bottom edge of the ring said cams are rendered less yielding than inwardly curved fingers on the lower edge of the ring would be, thus insuring a firmer retention of the ring when its cams are in engagement with those of the receptacle.-

In that embodiment of 'my invention shown in Figs. 5, 6 and 7; 1 represents a bottle or other receptacle having a ground glass stopper 13*, the bottle being unprovided with a cam formation around the top but having the usual projecting rib or flange 14 around the mouth. In order to adapt my invention for use in connection with such The rin member 7 a has an opening of greater iameter than the closing portion of the stopper 13 so that said ring member can be applied to the stopper from below, and a split ring 19 is also applied to the stopper, said split ring overlapping the shoulder of the stopper and underlapping the flange of the ring member 7, as shown in Fig. 7, whereby it provides not only a means whereby the ring member 7 can exert pressure upon the stopper, but also a means for preventing the i said ring member 7 from being detached from the stopper when the latter is removed from the bottle. This method of confining the rin member to the stopper may be adopted whether the cams 2 are formed on the receptacle itself or on a split ring applied thereto. 'VVhen 'it is desired to employ a lower rib inconnection with the ring having the cams 2 a s lit ring 5 may be properly disposed, and he d in osition by engagement with oifset or recesse portions of the tongues 17, asshown in Figs. 8 and 9, said tongues 17 constituting enlargements on the ring and having the notches 6* for the reception of the In s 11 on the ring member of the closure.

oth forms of closure or closure-retaining device which I have shown and described are cheap, they provide for the convenient application or removal of the ring member by a artial turn of the same, and they'insure the e ective retention of a sealing disk or ring in contact with its seat upon the mouth of therep which the receptacle may be provided.

,tudinally separated horizontal cams, convex below said earns a horizontal rib with offset ceptacle, or the secure confinement of a cap, stopper, cork, or other closing device with I claim: 1. The combination of a receptacle hav ing thereon externally disposed and longiin cross section and having cam-like ends, and a ring member having internally disposed and longitudinally separated elastic horizontal cams, concave in cross section and having cam-like ends, said concave cams engaging with the convex cams on the receptacle.

2. The combination of a receptacle having thereon externally, disposed and longitudinally separated horizontal cams, convex in cross section and having cam-like ends, and

thereon, with a ring member having internally disposed and longitudinally separated elastic horizontal cams, concave in cross section'and having cam-like ends said concave cams en aging with the convex cams on the an offset portion for engaging that of the rib on the receptacle to retain the ring member from rotary movement in either direction.

3. The combination of a shouldered stopper or other closure with a ring member having a flanged opening through which a portion of the closure can pass, and a split ring engaging said closure and interposed between said flan e on the ring member and the portion of the c osure which can pass through the opening within said flange.

4. The combination of a receptacle having 1 closure which can pass throng the opening within said flange, said ring member being provided with c'ams for engaging the cams on the receptacle to which the closure is adapted.

5. The combination of a receptacle having thereon externally disposed convex cams separated from one another by spaces which likewise have convex outer faces, and a ring member, having internally disposed and longitudinally separated elastic concave cams, which are adapted to engage with the rounded undersides of the convex cams on the receptacle and also with the convex faces of the spaces between said cams.

6. The combination of a receptacle having a flange-around the mouth, a split ring engaging said flange and having cams thereon, a shouldered stopper or other closure for the receptacle, a split ring applied to said closure, and a ring member engaging said second split ring and having cams for engagement with those of the split ring on the receptacle.

In testimony whereof, I have signed my name to this specification, in thepresence of two subscribing witnesses.
